What is Trenchless Technology? 

A minimally invasive construction process of installing new utilities, assessing existing infrastructure, and rehabilitating existing underground pipelines by eliminating or reducing excavations. This technology is commonly used for utilities such as water pipes, sewer mains and services, gas distribution lines, and electrical conduit. This construction method is an option to minimize environmental and social impact, as well as reduced construction costs.

Our design experience includes:

  • CCTV Condition Assessment

  • Lazer Profiling

  • Sonar

  • Ultrasonic testing

  • Horizontal Directional Drilling (HDD)

  • Auger Boring

  • Guided Auger Boring

  • Pilot Tube Microtunneling

  • Pipe Ramming

  • Micro-Tunneling

  • Direct Pipe

  • Pipe Bursting

  • Cured in Place Pipe (CIPP)

  • Sliplining

  • Coating (spray & hand application)

  • Spiral Lining

  • Chemical & Cementitious Grouting
